欧盟水框架指令实施20年成效分析及对我国绿色流域建设的启示

Effectiveness of EU Water Framework Directive after 20 years of implementation and enlightenments for green river basin construction in China

  • 摘要: 本文概述了欧盟2000年出台水框架指令的有关概念、流域管理计划及其主要内容,分析了欧盟地表水体生态状态和化学状态现状.结果显示,截至2021年底,欧盟仅有36.5%的地表水体达到生态良好或极好状态,30.3%的河流长度达到良好和极好状态,29.3%的地表水体达到化学良好状态,凸显其治理的长期性和复杂性.对我国绿色流域构建的启示主要有:强化生态监测体系,适当增加生物多样性指标;动态调整标准和目标,分阶段收紧污染物限制;以流域为单元统筹管理,协调各地区各部门逐步推进绿色流域建设.

     

    Abstract: Relevant concepts, basin management plans and main contents of the 2000 EU Water Framework Directive are outlined, with current ecological and chemical status of surface water bodies in the EU analyzed. Until the end of 2021, 36.5% of surface water bodies in the EU reached ecologically good or excellent conditions, 30.3% of river lengths reached good or excellent conditions. About 29.3% of surface water bodies are in good chemical condition. These data highlight the long-term and complex nature of water governance. Main inspirations that could be drawn from the EU directive are as follows. Ecological monitoring system needs to be strengthened, appropriate biodiversity indicators could be added. Standards and targets need to be dynamically adjusted, pollutant restrictions need to be tightened in stages. Watershed must be managed as a unit, various regions and departments should coordinate to gradually promote the construction of green river basins.
